London has been battered by 50mph winds that have felled trees and caused travel chaos. Powerful gusts swept across the capital as the Met Office issued a yellow "be aware" weather alert for most of the country.

“They’re very into each other, totally in love. She’s in Year 7, he’s in Year 9 at a different school.

“She is obsessed with him. She sees this as true love and they want to get married.”

Her friends reportedly had no idea the girl, who lives with her mother in north London, was pregnant when she suddenly stopped coming to school last month. It is understood she hopes to return in September to continue her education.

The source added: “Everyone is shocked. She was in school until March this year. She didn’t look pregnant. She’s only tiny anyway. She didn’t even have a bulge on her.

“Her mum is sticking behind her. She was a teenage mum as well – so she isn’t giving her any stick or being judgmental.”

Britain’s previous youngest mother Tressa Middleton fell pregnant at 11 and gave birth in Edinburgh aged 12 years and eight months in 2006. The youngest father on record is Sean Stewart, from Bedford, who was aged 12 in 1998 when his child was born.

The country’s previous youngest parents were April Webster and Nathan Fishbourne, both 14 when their son Jamie was born in south Wales in 2010.

The world’s youngest mother is Lina Medina from Peru who gave birth to her son Gerardo when she was just five years and seven months old in May 1939.

A total of 27,800 girls below the age of 17 got pregnant in England and Wales in 2012, but the numbers have fallen in recent years.

Figures released by the Office for National Statistics in February showed the UK under-18 conception rate remains the lowest since 1969 at 27.9 per cent per 1,000 women aged 15 to 17.

They also revealed that 253 girls under 14 fell pregnant in 2012, fewer than the previous year, with almost three-quarters having an abortion.
